I'm currently attempting to profile a non-rechargeable lithium battery on nPM PowerUP(2.2.3). When I start the profiling process, the charging stage is correctly skipped, and the battery enters the 15-minute rest period. After that, it begins the "Profiling at 25C" stage for five minutes exactly before failing with the message, "The profiling process was interrupted, as battery was disconnected while Profiling. Capacity consumed 0.00mAh." with LD4 quickly blinking. After pressing "Restart Profiling" I immediately receive the message, "Action Required: You must power the PMIC. Connect the battery and USB PMIC."
I have tried plugging in the PMIC cable and disconnecting/reconnecting the battery. While the log says "module_pmic: No response from PMIC," I assume the main issue preventing me from fulfilling the required action is the battery because after those five minutes, the fuel gauge on dashboard will say "Battery not detected" despite the battery being connected to the board. Additionally, I've bridged the NTC pin and 10kOhm pin with a jumper.
Before i proceed further, I want to confirm whether this issue is caused by using a non-rechargeable lithium cell. I've seen conflicting information: some posts suggest the nmp1300 and nPM Fuel Gauge Board can profile non-rechargeable batteries, though not officially tested, while others state that non-rechargeable batteries cannot be profiled at all.
Has anyone encountered this behavior or found a workaround? Is this failure expected using a non-rechargeable chemistry, or is there another underlying issue? Thank you!
